AXLE
The axle is secured to the frame rear section by means of especially foreseen screws, allowing to
regulate its position, in order to modify the sprayer trailer wheel base. The five holes machined on the
fastening plate allow to select three different axle positions, by 5,75 cm displacements.
The wheels’ axle shafts, inserted in the frame axle and locked by some special screws, allow to
regulate
the track width
, in order to fit it to the intervention requirements.
— The height with respect to the ground can be regulated. The misalignment between the axle shaft
and the wheels’ hub allows a variation of 12 cm. It is enough to turn the axle shafts.
After every regulation, carefully tighten all the screws and the bolts concerned by
the intervention.
WHEELS
. The wheels’ hubs are equipped with grease nipples for the bearings lubrication (see 14.1).
The tyres’ size and the operating pressure are indicated at step 4.5.2.
BEARING FEET
. They assure stability to the unit, when it isn’t coupled to the tractor.
The sprayer HAS NEVER to be uncoupled from the tractor before having correctly
positioned the bearing feet.
The BEARING FEET have always to be locked on “treatment position” during the unit
operation.
The bearing feet can be fastened to the sprayer in 2 different positions, according with the different
operational requirements:
Position A
-
front feet downwards and rear foot lowered:
THIS ALLOWS TO UNCOUPLE the
tractor
and assures the sprayer stability, when it isn’t coupled to the same one.
